• The inductance in a stepper-motor phase winding limits how fast current rises when power is applied. • Series-resistor current limiting needs higher voltages for faster step rates, but higher ...

I recently ran into an interesting dilemma while running tests on TI’s new InstaSPIN™-FOC sensorless motor control software. “How do you define motor torque?” On the surface, this sounds like an easy ...

This application note discusses the advantages and benefits in using a BLDC motor to drive a DC brushed motor. For a BLDC controller that uses hall effect devices, there are six steps in the ...

All the motors produce either interaction torque, reluctance torque or a combination of both. The second article in this series discussed the underlying principles common to all motors. As we have ...

The first type of motor built is still in widespread use In the late 1800s, several inventors built the first working motors, which used direct current (DC) power. After the invention of the induction ...

Torque ripple reduction in brushless DC motors is a subject of intense study due to its significance in enhancing the performance, efficiency and longevity of motor drive systems across various ...

Selection of replacement motors is usually straightforward if the ratings are equivalent. Sometimes, however, a different type of motor is necessary or desirable. For success in these cases, it is ...

Most known for their versatility, electric motors have revolutionised the way we view the core definition of power, qualifying it as effective energy expenditure concerning work done over time. Among ...

An adaptive algorithm kills jerky motions in motors. High-performance motion-control applications commonly use three-phase permanent-magnet synchronous motors, popularly known as brushless motors.
